PATENT JAMES P. DAVISON, OF ST. JOHN, ILLINOIS:

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 267,645, dated November14:, 1882.

Application filed September 22, 1882. (ModeL) To all whom it mayconcern:

Be it known that I, JAMES P. DAVlSON, of St. John, in the county ofPerry and State of Illinois, have invented a new and ImprovedGar-Coupling, of which the following is a full, clear, and exactdescription.

The invention consists in a draw-head provided with a swingingspring-latch partially crossing the end opening of the draw-head fromabove, and in a spring-hook latch partially crossing the draw-headopening from below, which lower spring-latch is provided at its rear endwith a tapering projection fitting into a notch in a disk mounted on atransverse shaft, which disk is provided opposite the notch with asegmental recess, into which a second disk passes which is mounted on atransverse shaft provided with a handle,whereby the hook-latch will belocked in position and cannot be lowered until the said handle isturned,

mit a movement of this lower hook-latch.

The invention also consists in combinations of parts, as will be fullydescribed and set forth hereinafter. L

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my improved draw-head. Fig. 2 isalongitudinal Fig. 3 is an end elevation of the same, and Fig. 4 is aplan view of the'same.

The draw-headA is provided with an opening beveled on the sides and onthe top and bottom, as shown in Figs. 2 and 3. 'Above the inner end ofthis beveled opening of the drawhead a transverse shaft, B, isjournaled, on which a curved latch, G, is mounted within the draw-head,and in such a manner that it pardraw-head.

tially crosses the middle of the inner end of the end opening of thedraw-head. The said latchUis provided with a shoulder, D,against which alever, E, rests, which is pressed downward by a spring, F, secured onthe side of the The shaft B is provided with an arm, B, on which aweight, 0, rests, which turns the lower end of the latch 0 toward theouter end of the draw-head. A hook latcb, G, is mounted on a transverseshaft, H, in the draw-head in such a manner that the longitudinal axisof the latch will be in a horizontal plane, and the hook end willproject into a slot in the inner end of the bottom bevel of the endopening of the draw-head, as shown in Figs. 2 and 3. A weight, H issuspended by means of a rod, H, from the lever H, and turns which diskis mounted on a transverse shaft,

N. The disk M has a segmental part cut off on one side, and at theopposite side it is provided with a notch, 0. A transverse checkstud, R,about in line with the shafts H' L N, and resting against the fiat edgeof the disk M, checks the movement of the same. The

shaft B projects from the side of thedraw head and is provided with ahandle, B, and

the shaft N projects from the draw-head and is provided with the handleN. a

The operation is as follows: To couple the cars the coupling-link S needonly be passed into the end openingofthe draw-head. It then comes incontact with the lower end of the latch G, and swings the sameinward inthe direction of the arrow at, and then drops intothe hook recess of thelatch G, which latch is held in a horizontal position, as shown. As soonas the end of the link S passes the hook '0 the weight 0 immediatelydraws the book downward again. The link will then beheld in thedraw-head and cannot be with drawn unless the latch (l is raised or thelatch G is lowered. To raise the latch O the handle B is turned in thedirection of the arrow 1). Then the link can be lifted out'of thehook-recess of the latch G. If the cars are to be uncoupled by beingdrawn apart, the latch G must be moved downward by the link as the sameis drawn from the draw-head. If the parts are in the position shown inFig. 2, this cannot take place. The disk M prevents the rotation of thedisk K, and the disk K holds the inner end of the latch-lever G.Therefore, to permit the movement of thelatch-lever G, the lever N mustbe turned in the direction of the arrow 0, so that the notch O of thedisk M will be opposite the segmental recess K of the disk K, therebyper mitting the disk K to movein the direction of the transverse shaftB, the latch O, the handle the arrow 01, the end of the projection Jonthe latch G can then move upward and the outer end of the latch G can bemoved downward by the link as it is drawn out of the draw-head.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with the draw-head A, ofthe transverse shaft B, the latch O, the leverE, and the spring F,substantially as herein shown and described, and for the purpose setforth.

2. The combination, with the draw-head A, of the latch 0, extendingpartially across the draw-head end opening from above, and thehook-latch G, extending partially across the draw-head opening frombelow, substantially as herein shown and described, and for the purposeset forth.

The combination, with the draw-head A, of the shaft B, the latch G, thearm B on the shaft B, the weight 0 on the arm B, and the latch G,substantially as herein shown and described, and for the purpose setforth.

4. The combination, with the draw-head A, of the latch U, the latch G,and the weight H substantially as herein shown and described, and forthe purpose set forth.

5. The combination, with a drawhead, of

B, the hook-latch G, the disk K, the disk M, the transverse shaft N,and. the handle N, substantially as herein shown and described, and forthe purpose set forth.

6. The combination, with the draw-head A, of the transverse shaft B, thelatch G, the hook-latch G, provided at its rear end with a projection,J, the disk K, provided with the notch J, and a segmental recess, K, thedisk M, having part out out and being provided with the notch O, theshaft N, and the handle N,

substantially as herein shown and described,

and for the purpose set forth.

7. The combination, with thedraw-head A, of the shaftB, the latch O, thehook-latch G, the weight H the disk K, the disk M, the shaft N, and thehandle N, substantially as herein shown and described, and for thepurpose set,

forth.

8. The combination, with the draw-head A, of the transverse shaft B, thelatch G, the hook-latch G, the Weight H the disk K, the disk M, and thecheck-stud R, substantially as herein shown and described, and for thepurpose set forth.
